I am trying to write a program for converting positive binary inputs into hex. in the hex output the point (".")is missing.
Suppose my expected output is e7.6 , but i am getting e76
only the "." is missing.
here is my BinToHex class..
import java.io.*; public class BinToHex { double tempDec,fractionpart; long longofintpart,templongDec; String input ="11100111.011"; String hexOutput=null,tempDecString,hex = null; static int i = 1;
I am trying to write a program for converting positive binary inputs into hex.Why am i getting this errors while compiling my binary to hex converter..
Exception in thread "main" java.lang.NumberFormatException: For input string: "148.0" at java.lang.NumberFormatException.forInputString(Num berFormatException.java:65) at java.lang.Long.parseLong(Long.java:441) at BinToHex.convertbintohex(BinToHex.java:24) at Test.main(Test.java:4)
Here is my BinToHex class
import java.io.*; public class BinToHex { double tempDec,fractionpart; long longofintpart,templongDec; String inpu ="1001.01"; String hexOutput,intpart,tempDecString,hex = null;
Following is the code for my assignment where a user inputs his full name in a string from keyboard. It should be done using BufferedReader. The program will give his initials as output.
############################
For example: User inputs-> Ram Kumar Das
Program Returns-> R.K.D.
I am written the following piece of code. It does not return the correct output. If "Ram Kumar Das" is given as input, it gives R.K.K. as output. Arrays and objects are strictly not allowed.
Java Code:
import java.io.*; public class Assignment { static int i=0; static BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); public static void main (String args[]) throws IOException
package Threads; public class Threads1 implements Runnable { public void run(){ System.out.println(" * * * * * "); } public static void main(String[] args) {
[code]...
Java Code:
new Thread(new Threads1()).start(); mh_sh_highlight_all('java');
should execute the thread associated with the run() and then the control should return to the next statement in the calling thread (the thread from which the other thread (associated with run()) was called); isn't it?
Write a Java program that reads a positive, non-zero integer as input and checks if the integer is deficient, perfect, or abundant.
A positive, non-zero integer, N, is said to be perfect if the sum of its positive proper divisors (i.e., the positive integers, other than N itself, that divide N exactly) is equal to the number itself. If this sum is less than N, the number is said to be deficient. If the sum is greater than N, the number is said to be abundant.For example, the number 6 is perfect, since 6 = 1 + 2 + 3, the number 8 is deficient, since 8 > 1 + 2 + 4, while the number 12 is abundant, since 12 < 1 + 2 + 3 + 4 + 6.
Is there a way that I can save a binary search algorithm to a text file or something, so that it will always contain more information? The reason why I ask this is because I have BST like project which is supposed to act the game Twenty Questions, were it asks a person 20 Q's until it guess the answer. However, although my project does not require you to save stuff to a file, I find it rather very useful and cool if I could do that.So for example it would start out something like this:
Think of an animal and I will guess it. Does it have legs? YES Is it a cat? YES I win! Continue? YES
Think of an animal and I will guess it. Does it have legs? NO Is it a snake? YES I win! Continue? YES
Think of an animal and I will guess it. Does it have legs? NO Is it a snake? NO I give up. What is it? EARTHWORM Please type a question whose answer is yes for an earthworm and no for a snake. DOES IT LIVE UNDERGROUND? Continue? YES
Think of an animal and I will guess it. Does it have legs? NO Does it live underground? NO Is it a snake? NO I give up. What is it? FISH Please type a question whose answer is yes for an earthworm and no for a snake. DOES IT LIVE IN WATER? Continue? NO Good-bye.
However, if the user exits the program then everything will be lost and go to waste. So once again, is there a way that I can save all of these inputs to a file or something and then read it in again?
I first time tried Java web service sample example using eclipse with axis2. First i wrote the provider class. Then by clicking create Web Service from the provider class It will show the following error "IWAB0014E Unexpected exception occurred." I have attached the screenshot for reference.
I am new to java and programming in general. I figured out how to convert an integer input to binary however I am having issues doing the opposite of converting a user input binary number to a decimal.
I need to do this with basic math (or string depending on how I represent the binary) and no functions.
I know how to convert binary to integer on paper but I am having a hard time working it out in java.
This code is for a GUI Java program that is supposed to convert back and fourth between two numbering systems. For example, binary to decimal or decimal to binary. I have created methods for some of the conversions however, I could successfully develop a method to convert from hex to binary. If you plan to run it to see what happens to the current method that I made please know that in the GUI the north end from left to right is as follows.
The textfield is for user entry of any type of data. The first combobox is for the user specifying to the program what type of data he or she entered. The second combobox is for the user to choose what he wants that data converted to. The button is to convert it. The south side has a textarea that gives out the results. Please note that only some of the conversions work so far. There are comments in the code to label which methods do what converisons. Need to find a method that will convert from hex to binary, what is wrong with the current method.
There's a main menu choosing binary,octa,hexa,and decimal if i choose decimal it will display decimal menu and then i will input the numbers of binary and then it automatically display the converting process for octa hexa and decimal. and if i choose octa . It display the octa menu and i will input the numbers in octa and then it automatically display the converting process for binary hexa and decimal.. and so on.. but in binary if i input 2 it will display invalid .. the same as octa hexa and decimal... in my code the only problem is the converting process. our instructor said no one will use a converter for our project. we will code it manually ..so for a moment .. this is my code..
import java.util.*; import java.lang.*; public class mainmenu { public static void main (String[]args) { Scanner in = new Scanner(System.in); char B, O, H, D, Q, L, N , Y; char bin , pk, pick ;
Write a java program that will ask a user to input grades until the user inputs the sentinel value -1. The program should test each input to determine whether 0<=grade<=100. If the grade entered is within this range, the program should print "Grade accepted;" if not, the program should print "Invalid input".
import java.util.Scanner; public class FindHexString { public static void main(String[] args) { String hexString = ""; //output a hex string int decNumber;//decimal number to be converted int storeInput; //copy f input decimal number

I am trying to figure out how to convert from decimal to hexadecimal without using the java library function. This is just a guess. I could be wrong.
I created this program to display a square root table. Problem is all of my output is too long. I would like to round the number to 4 spaces past the decimal. Here is my code:
I am attempting to write a program that accepts input of a positive integer, reports each digit and then the sum of all digits. This is what I have so far:
*/ package numbersum; import java.util.*; public class Week4NumberSum { static Scanner console = new Scanner(System.in); /** * @param args the command line arguments
[Code]...
It works if I enter 1234567891 (10 digits) Enter a positive integer: 1234567891 digit: 1 digit: 2 digit: 3 digit: 4 digit: 5 digit: 6 digit: 7 digit: 8 digit: 9 digit: 1
The sum of the digits is 46
But if I enter 11 digits, it fails:
Enter a positive integer: 123456789123 (12) Exception in thread "main" java.util.InputMismatchException: For input string: "123456789123" at java.util.Scanner.nextInt(Scanner.java:2123) at java.util.Scanner.nextInt(Scanner.java:2076) at week4numbersum.Week4NumberSum.main(Week4NumberSum. java:26)
java - Scanner error with nextInt() - Stack Overflow gives me some infor for InputMismatchException - which I find described as In order to deal with this exception you must verify that the input data of your application meet its specification. When this error is thrown, the format of the input data is incorrect and thus, you must fix it, in order for your application to proceed its execution.
I don't understand why the 10 digit integer is OK but the 11 or > digit integer is a mismatch.
I am trying to write a program in Java that uses threads.Below is the program requirements:The goal of this assignment is to create a routine which creates multiple threads, has them do work in parallel, and terminates when the last thread has finished.
The Scenario: There are several groups of people in a bar watching the Olympics cheering for their country. Each group will cheer for their country some given number of times, with a random pause (between 2 and 5 seconds) between each cheer. There is enough room at the bar for up to ten different groups to sit (each would be cheering for a different country).
The Program: The task is to write a program that will simulate these cheers using threads. The program should be called cheer.X (X being the language of choice). You may use any language that supports threading. When the program is run it should ask for the number of countries and then the name and how many times it will be cheered for. The main function will then create a thread for each team and each thread is responsible for cheering the specified number of times for the correct team at the random interval. You will submit the proper source code file for me to open and compile myself, not an executable.
An example run would look something like this: How many countries are supported at the bar? 3 Enter the first: China How many cheers? 2 Enter the second: USA How many cheers? 4 Enter the third: Russia

Write a program (TwoIntegers.java) that prompts the user to enter two positive integers and prints their sum (by addition), product (by multiplication), difference (by subtraction), quotient (by division), and remainder (by modulation). When the user enters 5 and 3, the output from your program should look exactly like the following:
Enter two positive integers: 5 3 The sum is 8. The product is 15. The difference is 2. The quotient is 1. The remainder is 2.
import java.util.Scanner; public class TwoIntegers { public static void main(String[] args) { System.out.println("Enter two positive integers: "); Scanner userInput = new Scanner("System.in"); int integer1 = userInput.nextInt(); int integer2 = userInput.nextInt();
So I am trying to write the output of two different java class files to one txt file while the program runs. The file name is determined before the program is ran, through the command prompt as arguments. How can I get the second class file to edit the same txt file without running into compile errors.
For right now I'm just going to send everything that the second file outputs to a message String variable, so that the Main class outputs to the the text file. I still want to learn how to write to the same text file directly from the second class file.
import java.io.*; public class Test{ public static void main(String[] args) throws IOException{ int x; //create a new file internally called doc. But externally labelled the user input File doc = new File(args[0]); if (doc.exists()){
I have an assignment where I'm supposed to write a program where the user inputs a month between 1-12 and then the right amount number in every month. I've tweaked the code a bunch of times, but I keep getting this error message:

I think I have just forgot to put in a few { } symbols, maybe an open loop?
Develop an algorithm for a Java program that takes as input a single letter and displays the corresponding digit on the telephone. The letters and digits on a telephone are grouped this way:
The screen dialog might look like this: Enter a single letter, and I will tell you what the corresponding digit is on the telephone. R The digit 7 corresponds to the letter R on the telephone.
The program should display a message indicating that there is no matching digit for any non-alphabetic character entered by the user. Also, the application should recognize only uppercase letters. If a user enters a lowercase letter, the program should display an error message. Prompt the user with an informative message for the input value as shown above.
The application should include the input letter as part of the output.
Write the algorithm to solve this problem including steps for prompting the user, getting input from the keyboard, and displaying the results.
Write the Java program that you designed, using your algorithm as a guide. Use your algorithm as comments in the body of the main method.
Use proper indentation, and meaningful identifiers throughout the code.
1.Write a JAVA program that will input 10 scores and output the Highest and Lowest score.
2.Write a JAVA program that will input the base and power and display the result: Example: Base is 4 Power is 2 the answer is 16 (Note: Math.pow( ) method is not allowed)
3.Write a JAVA program that will input an integer number, and then will output the sum of all inputted numbers. The program will stop in accepting inputs if the user entered 0.
Technically, when you run the program, a gif page appears (that I put as a placeholder) and when you press the letter 'n' JCreator runs the program, displaying a character P on a .txt field made using the Notepad on Windows. You can move it left, right, down, and up andf it will move accordinly. However, each time I make such action, the compiler has to rewrite to whole .txt field with the new position.
My former tutor said that in order for it to be "real-time", we have to use an applet.
The idea behind this program is that the program prompts the user to input an initial base (2-36), which checks to ensure that it is a valid int, then asks for a number to convert (which is taken as a String), then it asks which desired base the user would like to convert said number to. I have a basic program that is not complete, but allows me to do a few conversions using convertTo. I believe that I am going to have abandon this method and try mathematically converting every number. This leads me to what I can and cannot do. I am unable to use the initialBase as a condition to know what kind of number i an converting. For instance, I don't know how to make program know that if "2" is the initialBase, that that means that the String is a binary number. THAT is what I'm having problems with.
Here is my initial program that has a few things that are copied and pasted from other bits of my code in my program:
XML Code: Url...
I have broken down what I (think I) need to do here: Check to see if the input base is 2, 8, 10, 16, or 32. Hint: Put the possible bases in an array, and check the input base against the array. Check to see if the input number is valid for the base. Hint: Create a String "0123456789ABC...V" and compare each input character with the first "base" characters of the String. Check to see if the output base is 2, 8, 10, 16, or 32. Hint: Use the same possible bases array you used in step 1 to verify the input base.Check to see if the input base is equal to the output base. If so, print the input number. Perform a conversion from the input base to base 10. Perform a conversion from base 10 to the output base. You do this in 2 steps because it's easier to check each conversion separately.Output the converted number.
